The download includes the mesh, a swatch and two sets of 8 recolours. The two sets are identical except one is categorised as formal, and you absolutely need Chris's mod to plan and dress the infant in this; the other is categorised as casual and formal, and is also townified, which will make it be randomly selected for newborns even without the mod (but without the mod, you'll of course not be able to change it). You can only use one recolour from either set.
